--enable-simd=code setup Grid for the SIMD target `<code>`(default: `GEN`). A list of possible SIMD targets is detailed in a section below.
--enable-gen-simd-width=size select the size (in bytes) of the generic SIMD vector type (default: 32 bytes). E.g. SSE 128 bit corresponds to 16 bytes.
--enable-precision=single|double set the default precision (default: `double`).
--enable-precision=single|double set the default precision (default: `double`). **Deprecated option**
--enable-comms=mpi|none use `<comm>` for message passing (default: `none`).
--enable-rng=sitmo|ranlux48|mt19937 choose the RNG (default: `sitmo`).
--disable-timers disable system dependent high-resolution timers.
